This is an encoder for the Plessey Code. According to the Plessy Code
Specification, numeric digits are assigned a set value, but the remaining values
can be used for whatever values are desired. This subclass adds the ability
to encode the letters A through F for full hexadecimal support.

<CODE>Wide bar followed by narrow space is a "1" bit.<BR>
Narrow bar followed by wide space is a "O" bit.</CODE>
<br><br>
We will use a 3:1 wide to narrow bar ratio.
